Aubrey Plaza voices Grumpy Cat in “Grumpy Cat’s Worst Christmas Ever”

Cat's out of the bag: Sometimes grumpy people are great for a laugh. Granted, the grumpy folks probably aren't the ones laughing, but as film classics like "Grumpy Old Men" (1993) show, other people's surliness sure can be a rib tickler.

Well, if grumpy people are so funny on screen, just imagine what a grumpy cat would be like. That's right, the Internet sensation Grumpy Cat, who's quite possibly the most famous feline in the nation today, is getting her very own TV movie on Lifetime.

"Grumpy Cat's Worst Christmas Ever" will be bringing the sour-faced mouser to the screen this holiday season, and in the spirit of the good-natured fun of it all, a popular actress and comedian has signed up to voice the furry little star.

Aubrey Plaza, one of the stars of NBC's Thursday night comedy "Parks and Recreation," will be starring as the voice of Grumpy Cat. Known for her deadpan humor, the young actress also appeared in the NBC comedy "Welcome to Sweden" and has done voice work in the animated favorite "The Legend of Korra."

She had smaller roles in some big screen films, too, including "Scott Pilgrim vs. the World" (2010) and "The End of Love" (2012), before landing her first starring role in 2012's "Safety Not Guaranteed."

So Plaza's clearly cut out for this job, but what about Grumpy Cat herself? Well, the kitty (whose name is actually Tardar Sauce), who was blessed with a dour facial expression, has appeared on the covers of both "The Wall Street Journal" and "New York" magazine, and she appeared on national TV programs including "Today" and "Good Morning America."

With a successful book and calendar, a place of honor in an episode of "American Idol" and the love of people across the world, this Internet sensation is well placed to take Christmas by storm. Watch for "Grumpy Cat's Worst Christmas Ever," starring Tardar Sauce (a.k.a. Grumpy Cat) and Aubrey Plaza, this holiday season on Lifetime.

A chance of Frost: There's a 100 per cent chance that "Doctor Who" watchers will be experiencing some Frost this holiday season.

"Doctor Who's" Christmas special is always a delight for fans of BBC's science fiction fan favorite, and it never fails to bring out the guest stars. This year is no exception: Nick Frost, Nathan McMullen and Michael Troughton will be joining the Doctor himself, Peter Capaldi ("World War Z," 2013), when it airs this holiday season on BBC America.

Frost is probably the best known actor of the trio outside of the U.K., with roles in some modern-day classic films to his name. He's had roles in "Shaun of the Dead" (2004), "Hot Fuzz" (2007), "Pirate Radio" (2009), "Snow White and the Huntsman" (2012) and 2013's "The World's End." He's done voice work, too, with roles in "The Adventures of Tintin" (2011), "Ice Age: Continental Drift" (2012) and 2014's "The Boxtrolls."

McMullen may not be well known on this side of the Atlantic, but in the U.K. he's recognized for his work in the teen drama "Misfits," while Troughton has long been a regular on TV screens in the U.K., including appearances in "Minder" and "The New Statesman." He has a "Doctor Who" connection, too: he's the son of Patrick Troughton, who famously played the second incarnation of the Doctor in the 1960s.

With a bevy of guest stars and exciting stories, the "Doctor Who" Christmas specials are always fan favorites. With a new Doctor on screen this season, there's even more to look forward to this holiday season on BBC America.

The music never dies: The story of Aaliyah's life is one of tragedy and an early departure from the world, but the musical sensation's legacy still lives on to this day.

Hers is a story that has captivated pop music fans for over a decade, and now Lifetime is bringing that story to the screen. "Aaliyah: The Princess of R&B" will premiere on the network Saturday, Nov. 15.

Based on "Aaliyah: More Than a Woman," the bestselling book by Christopher John Farley, "Aaliyah: The Princess of R&B" has cast Alexandra Shipp ("House of Anubis," "Alvin and the Chipmunks: The Squeakquel," 2009) in its starring role.

Aaliyah grabbed the nation's attention when she appeared in "Star Search" at the young age of 10, and she quickly went on to become an R&B musical sensation. Tragically, her life was cut short in 2001 when a plane carrying her and members of her crew crashed in the Bahamas.

Also cast to appear in the two-hour film are Rachael Crawford ("Continuum"), A.J. Saudin ("Degrassi: The Next Generation"), Sterling Jarvis ("Nikita"), Lyriq Bent ("Rookie Blue"), Anthony Grant ("The Listener"), Izaak Smith ("Marmaduke," 2010) and Elise Neal ("The Hughleys").

Aaliyah's story is one of a young life cut short right at the height of her success. She was a woman who found enormous success very early in life, and now that story will be coming to the small screen. "Aaliyah: The Princess of R&B" airs Saturday, Nov. 15, on Lifetime.
